“…The SSS affects the service life of structures under the static and cyclic loading (Kogaev et al 1985). Under the compression, uniaxial tension or shear, the material strength criteria can be different for different SSS types (Smirnov-Alyaev, 1968;Tsvik et al, 1978), which requires to use unified strength criteria and various limit state equations (Kogaev et al 1985;Pisarenko et al;2008;Lebedev et al,2003;Tsvik, & Zenkov, 2015a,b, 2018Zenkov, 2017).…”

A study of the stress-strain state (SSS) of disc specimens has been conducted when testing specimens with stress concentrators (grooves). The research has shown that the truncation of circular discs along two symmetrical chords makes it possible to change the type (the ratio of principal stresses) of SSS that occurs at the destruction site. Therefore, these specimens can be used to assess the structural strength of materials on standard single-drive testing machines, taking into account the real type of SSS that occurs in the bearing elements of machines. The results of numerical SSS modeling have been used to build the dependences of the SSS type and level on geometric parameters of specimens. Geometrical parameters can be chosen for a certain SSS type to assess both the static and fatigue strengths of materials used in the manufacture of bearing elements.
